NOTE:
* A file auto-cache feature has been added but is not currently active.
So for the meantime make sure to save your work before closing the
application.
This feature will be active in 0.4, allowing you to close and open the
application without loosing unsaved data.

I just tested your program, and I really have to congratulate with you. The feeling of quality is just everywhere, from the custom made keyboard, to the files menu. When I discovered I had to swipe with my finger the list, rather than selecting with the buttons, I really felt like being on an android device. This is the kind of quality level the PSvita deserves, well done!
